GAS-BURNER.

SPECIFICATION forming part of. Letters Patent No. 305,535, datedSeptember 23 1884.

Application filed lio vemhel 9, 1883 (Ne model.)

gas-burners,and its object is to produce a flame of great brilliancy andpower with a small consumption of gas. I

The distinctive characteristics of the invention and its mode ofoperation will appear in full hereinafter, reference being' had to theaccompanying drawings, in which A Figure l'is a central verticallongitudinal section of a gas-burner embodying the. elements of theinvention. Fig. 2 isa top View of the same. Fig. 3 is a view of the rollof wireeloth detached from the flametube. Fig. 4. is a top and side iewof the chimney made in sections, and Fig. 5 is a side and sectional viewof a modified form of burner.

In the drawings,A denotes the pipe leading from the source ofgas-supply, and upon the end of the pipe is the burner proper, whichconsists of a suitable frame, hereinafter described, inclosingtheherizontal fiametube B,

which is connected with the horizontal tube 0 by the series ofsmallwertieal tubes D, the tube 0 being in communication with thesupply-pipe A. The flame-tube B will be perforated along its upper edge,will be supplied in its interior with a roll of fine wirecloth, F,

or equivalent material, and will, preferably, have screw-caps E at itsends. The wire-cloth or other material will be rolled up and inserted inthe tube, the screw-cap on one or both ends being afterward applied. Thepurpose of the wire-cloth is to retard and superheat the gas, ashereinafter pointed out.

Any number desired of the connecting-tubes D may be employed; or, inlieu of them, I mayv connect the tubes B O by a flat metal tube, asindicated in Fig. 5, this latter being either made a part of the tubes BO or independent thereof, as may be preferred.

The frame of the burner consists of the bowl-. shaped foraminous plateG, surrounding the base of the burnerand supporting the deflector 1-1and vertical frame I which carries the deflector J, the air retardingand heating plate K, and the flange L, uponwhich the chimney rests. Thelower portion of the bowl-shaped part G is cut to receive the tubecommunieating with the tube 0, and along the upper inner horizontal edgeof said part G is secured the deflector H. The vertical frame I extendsupward from the outer edges of the horizontal portion of the plate G. Itis perforated throughout, and at about its center is secured the upperdeflector, .I,which consists of the horizontal. perforated portion Mandthe upwardly and inwardly deflected portion N. Around the upper edgeofthe vertical frame I is the flange L,for sustaining the chimney, andfrom one end of the frame I to the other extends the elongated frame. orplate K, the center of which is removed to permit the passageof theflamethroughit, and its outer edges areseparated from the flange L byaspace, S through which air may pass along the inner surfaces of thechimney. or globe. The frame K will preferably be perforated, asindicated, audits office is to retard and partially heat the current ofair and turn part of it into the flame, the other and cooler portion ofthe current being permitted to pass gently upward over the inner surfaceof the globe or chimney.

The fingers or devices employed for retaining the chimney or globe inplace will besuch' as are best adapted to the purpose and to the shapeof the chimney. Irecommend the employment of a chimney having fiat sidesand flat or oval ends, the whole describing in crosssection an outlinesubstantially in the form of oblong square.

the drawings, and lettered a b c d, respectively, and when thusconstructed the retaining fingers 6 will be of proper form and width tocover the joints made by the sections, and will preferably extend to thetop of the chimney, b i her nec ed y a n r w s r p of metal to preventtheir being sprung outward. There is a great advantage in making thechimney in sections, as describedand it is This chimney may be made 7 inone piece or in four sections, as shown in that one part of the samemaybe of colored or s e lass an he o r P Of r f ng a s or that,the chimneymay be made wholly of tube 0, whence the heat is communicated to theforaminous bowl-shaped plate G, and in a lesser degree to the verticalframe I, the upper part of the frame being much cooler than the lowerpart. The flame heats the deflectors H J and frame K. It will be notedthat the gas is heated in the tubes B, O, and i 5 D, and is thoroughlydiffused before its escape, and that :[he air passing through the heatedperforated parts of the frame and circulating about said tubes will alsobe greatly heated and then deflected into the base or hydrogen part ofthe flame. That part of the air which is deflected inward by the frame Kenters the flame, while the air which enters through the perforatedframe I and the perfoations in the deflector J and passes upward throughthe air-space S is comparatively cool. The frame K, however, breaks upany strong drafts, and heats and turns part of this previously-cool airinto the. flame. The parts of the burner and frame are constructed andarranged with a View of so superheating the gas and tempering the airatdifferent points that a broad strong brilliant flame will beproducedand give forth a clear pervading light. As an illustration, Iwill say that with a flametube two and one half-inches in length andcontaining twenty-seven apertures I have had no difficulty in producinga beautiful flame two and one-half inches in width and four and one-halfinches in height from six feet of gas per hour. Of course the flame-tubemay be of any length required, the foregoing dimensions having beengiven mainly with a View of conveying an approximate idea of the capacity of the invention.

In Letters Patent granted to myself April 10, 1883, and numbered275,708, I illustrate an elongated flame-tube connected with thegas-pipe by smaller tubes; but in said patent the elongated flame-tubedoes not contain a roll of gas retarding and superheating substance, andthe light is probably not so desirable as that produced by the presentflametube. In the patent to Allen, No. 10,270, datedNovember 29, 1853,is shown an elongated flametube containing a wick inclosed in wiregauze.This patent is for a lamp, and the wick is kept moist by actual contactwith the fluid, which is conveyed through a tube to the wick. Thewire-gauze causes the oil to spread uniformly through the wick, andprevents it from burning. According to my invention the roll of gasretarding and superheating substance is essentially different from thatshown in the patent to Allen and de- '65 scribed therein as a wickinclosed by wiregauze. If this wick and gauze were 'placed in applicantselongated flame-tube, it would not serve to superheat the gas, but thewick would be rapidly destroyed, and the shell of wire-gauze wouldneither retard the flow of nor superheatthe gas. The roll of wire clothF used by applicant in the flame-tube must be sufficiently dense toretard the flow of gas, and hence it is called a roll, to distinguish itfrom a mere tube of wire-cloth. 7 5

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a gas-burner, the elongated horizontal tube B, containing a rollof gas retarding and superheating substance, and connected by means ofthe series of tubes D and tube Gwith a gassupply, substantially assetforth.
